  POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9699919799/functions/openat.html}
  
  Gnulib module: openat
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  glibc 2.3.6, Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8,
  AIX 5.1, HP-UX 11, IRIX 6.5, Cygwin 1.5.x, mingw, MSVC 14.
  But the replacement function is not safe to be used in libraries and is not multithread-safe.
  @item
  Some platforms do not support @code{O_CLOEXEC}:
  AIX 7.1, Solaris 10.
  @item
  On platforms where @code{off_t} is a 32-bit type, @code{open} may not work
  correctly with files larger than 2 GB@.  (Cf. @code{AC_SYS_LARGEFILE}.)
  @item
  This function does not fail when the file name argument ends in a slash
  and (without the slash) names a nonexistent file or a file that is not a
  directory, on some platforms:
  Solaris 9.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  The Gnulib replacement for @code{O_CLOEXEC} is not atomic, and so is
  not safe in the presence of multiple threads or signal handlers.
  @item
  @code{openat (fd, "symlink", O_NOFOLLOW ...)} fails with @code{errno}
  set to @code{EMLINK} instead of the POSIX-required @code{ELOOP} on
  some platforms:
  FreeBSD 10.1.
  @item
  @code{openat (fd, "symlink", O_NOFOLLOW ...)} fails with @code{errno}
  set to @code{EFTYPE} instead of the POSIX-required @code{ELOOP} on
  some platforms:
  NetBSD 6.1.
  @end itemize
